Dual energy CT (DECT) has been evaluated for the assessment of focal and diffuse liver disease. By using the spectral information of DECT iodinated contrast media can be selectively visualized to improve the conspicuity of enhancing focal liver lesions, or to suppress the iodine signal to create a virtual non-enhanced CT data set. Furthermore, already in the eighties of the last century, DECT has been evaluated for the assessment of diffuse liver disease such as fatty liver and iron overload. The following chapter reviews the basic principles, clinical protocols, and scientific evidence of hepatic imaging using DECT.
